Party Must Submit Material Information to USPTO
Note:
Parties must submit any reviewed document that is material to the patentability of a pending matter before the Office to the USPTO.

Accordingly, each party presenting a paper to the USPTO, whether a practitioner or non-practitioner, has a duty to perform an inquiry that is reasonable under the circumstances. This reasonable inquiry may comprise reviewing documents that are submitted to or received from other Government agencies, including the FDA. If any reviewed document is material to the patentability of a pending matter before the Office, such as a patent application (including a reissue application), or a reexamination proceeding, the party has a duty to submit the information to the USPTO. 37 CFR 1.56, 1.555, and 11.18(b)(2). A duty of reasonable inquiry may exist based on circumstances known to the party presenting the paper to the USPTO. Failing to inquire when the circumstances warrant it could result in sanctions or other action under 37 CFR 11.18(c), which may include: (1) striking the offending paper; (2) referring a practitioner’s conduct to the Director of Enrollment and Discipline for appropriate action; (3) precluding a party or practitioner from submitting a paper, or presenting or contesting an issue; (4) affecting the weight given to the offending paper; or (5) terminating the proceedings in the Office. See, e.g., In re Hao, Proceeding No. D2021-14 (USPTO Apr. 27, 2022) (involving disciplinary sanctions predicated on non-compliance with 37 CFR 11.18). See also MPEP § 2015.

Material Information for Patent Review
Note:
Submit relevant documentation to the Office if it is material to any pending patent application or reexamination proceeding, especially when submitted to a regulatory body like the FDA.

Where relevant documentation is submitted to a regulatory review body, such as the U.S. Food & Drug Administration (FDA), and is material to any pending patent application or reexamination proceeding, such documentation should be submitted for Office review. While the considerations made by the FDA for approving clinical trials are different from those made by the USPTO in determining whether a claim is patentable, submissions, particularly any assertion that is made which is contradictory to assertions made to the examiner, may be material to ongoing patent proceedings. Belcher Pharmaceuticals, LLC v. Hospira, Inc., 11 F.4th 1345, 1353-54, 2021 USPQ2d 909 (Fed. Cir. 2021). See also MPEP § 2164.05. Duty of disclosure may require that if the actual filing date of an application is after the date of the applicant’s date of marketing approval by FDA, and the applicant intends to list any resulting patent in the orange book for that product, informing the USPTO during examination of the application of that intent and applicant should consider providing the Paragraph IV “factual and legal basis” notice to USPTO.

Contradictory Assertions Material to Patents
Note:
Submissions, especially those contradictory to FDA assertions, must be disclosed in ongoing patent proceedings.

Where relevant documentation is submitted to a regulatory review body, such as the U.S. Food & Drug Administration (FDA), and is material to any pending patent application or reexamination proceeding, such documentation should be submitted for Office review. While the considerations made by the FDA for approving clinical trials are different from those made by the USPTO in determining whether a claim is patentable, submissions, particularly any assertion that is made which is contradictory to assertions made to the examiner, may be material to ongoing patent proceedings.
